Tay-Sachs
Noun: A rare, inherited, and fatal disorder that destroys nerve cells in the brain and spinal cord. It is caused by the absence of a vital enzyme, leading to the harmful accumulation of fatty substances (lipids) in nerve tissue. The disease is most commonly associated with individuals of Ashkenazi Jewish descent.

It is typically used in medical, genetic, and familial contexts. * All newborns in the community are screened for Tay-Sachs disease. * The couple sought genetic counseling due to a family history of Tay-Sachs. * Research into therapies for Tay-Sachs is ongoing.
